Gastrointestinal Carcinoid Tumors Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview


The way the chemotherapy is given depends on the type and stage of the cancer being treated.

Hormone therapy

Hormone therapy with a somatostatin analogue is a treatment that stops extra hormones from being made. GI carcinoid tumors are treated with octreotide or lanreotide which are injected under the skin or into the muscle. Octreotide and lanreotide may also have a small effect on stopping tumor growth.

Treatment for carcinoid syndrome may also be needed.

Treatment of carcinoid syndrome may include the following:

  • Hormone therapy with a somatostatin analogue stops extra hormones from being made. Carcinoid syndrome is treated with octreotide or lanreotide to lessen flushing and diarrhea. Octreotide and lanreotide may also help slow tumor growth.
  • Interferon therapy stimulates the body's immune system to work better and lessens flushing and diarrhea. Interferon may also help slow tumor growth.
  • Taking medicine for diarrhea.
  • Taking medicine for skin rashes.
  • Taking medicine to breathe easier.
  • Taking medicine before having anesthesia for a medical procedure.

Other ways to help treat carcinoid syndrome include avoiding things that cause flushing or difficulty breathing such as alcohol, nuts, certain cheeses and foods with capsaicin, such as chili peppers. Avoiding stressful situations and certain types of physical activity can also help treat carcinoid syndrome.

For some patients with carcinoid heart syndrome, a heart valve replacement may be done.

New types of treatment are being tested in clinical trials.

This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI Web site.

Targeted therapy

Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Several types of targeted therapy are being studied in the treatment of GI carcinoid tumors.

Patients may want to think about taking part in a clinical trial.

For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
